However, the book wasn’t as it seemed and after Vincent reads the book, it teleports him to the world the book depicts. A world of sword and magic with a horrible twist. Heroes are referred to as invaders, so people hate, persecute, and kill any otherworldy hero summoned to their world.

As an oddity to the world and possessing an oddity residing in his body, Vincent becomes the only person in the world to awaken two classes. A Hero and a Mutation class. The more retainers he acquires, the stronger he becomes through mutation.
